Abstract

Enlightened by Zhang and Cheung’s original idea [J.
Phys. B 41, 015503 (2008)], we put forward a novel tripartite quantum
information splitting scheme by using three Einstein-Podolsky-Rosen
pairs as quantum channels. Our scheme is applicable for perfectly
splitting four ensembles of quantum information known by the
splitter in priori. In contrast to the general scheme using the same
quantum channels [Eur. Phys. J. D 39, 459 (2006)], our
scheme has distinct advantages in quantum resource consumption,
quantum operation intensity, classical communication cost and
efficiency when dealing with the four specific ensembles of quantum information.
